I have seen some drives that R_ERR in the middle of a DMA transaction and
then don't send the FIS to update the shadow registers in the controller.
You could be seeing this problem, but you'd need to look a SATA bus trace to
be sure.

This message is from the T13 list server.


What causes a PCI bus SATA controller to stop responding in the
middle of a command? Specifically, in the middle of a READ DMA
command, what would cause the drive status to change to FDH or FFH
and then cause the controller and drive(s) to ignore a Soft Reset and
continue to return status of FFH for all reads of any ATA register?
